There are different variables that creates proper conditions for long-term prognosis of implant treatments.\n\nImplant position and surrounding bone around them, have been described in scientific literature to be key factors in the longevity of those treatments.\n\nIt has to be defined the \\"critical bone thickness\\" around implants. It basically means that implants has to be completely surrounded by bone, that will serve as protection. If the implants are not surrounded by bone, procedures as guided bone regeneration may be performed.\n\nThose procedures can be executed before or simultaneously during the implant placement. In the standard procedure, the simultaneous guided bone regeneration during implant placement requires to leave the implant and the regeneration healing below the gingiva, needing a second surgery for accesing to those implants.\n\nIn this randomized controlled trial the hypothesis is to discover if not submerging this regenerations may show the same results than submerged ones.\n\nFor that, the objective is to study the different variables around these regeneration to evaluate the performance of non-submerged protocol.",[75,76,77,78],"Guided Bone Regeneration","Dental Implant","Submerged Regeneration","Bone Atrophy","NOT_YET_RECRUITING","2024-11-16",{"date":82,"type":83},"2024-11-19","ACTUAL",{"date":85,"type":69},"2024-12-15",{"date":87,"type":69},"2026-06-06",{"name":5,"class":6},1]
